  • Patent number: 11086182
    Abstract: Certain aspects pertain to methods of fabricating an optical device on a substantially transparent substrate that include a pre-deposition operation that removes a width of lower conductor layer at a distance from the outer edge of the substrate to form a pad at the outer edge. The pad and any deposited layers of the optical device may be removed in a post edge deletion operation.

  • Patent number: 11065845
    Abstract: Methods of manufacturing electrochromic windows are described. Insulated glass units (IGU's) are protected, e.g. during handling and shipping, by a protective bumper. The bumper can be custom made using IGU dimension data received from the IGU fabrication tool. The bumper may be made of environmentally friendly materials. Laser isolation configurations and related methods of patterning and/or configuring an electrochromic device on a substrate are described. Edge deletion is used to ensure a good seal between spacer and glass in an IGU and thus better protection of an electrochromic device sealed in the IGU. Configurations for protecting the electrochromic device edge in the primary seal and maximizing viewable area in an electrochromic pane of an IGU are also described.

  • Patent number: 11030929
    Abstract: The embodiments herein relate to methods for controlling an optical transition and the ending tint state of an optically switchable device, and optically switchable devices configured to perform such methods. In various embodiments, non-optical (e.g., electrical) feedback is used to help control an optical transition. The feedback may be used for a number of different purposes. In many implementations, the feedback is used to control an ongoing optical transition. In some embodiments a transfer function is used calibrate optical drive parameters to control the tinting state of optically switching devices.

  • Publication number: 20210163346
    Abstract: Methods for protecting transparent electronically conductive layers on glass substrates are described herein. Methods include depositing a sacrificial coating during deposition of the transparent electronically conductive layer, before packing the glass substrate for storage or shipping, after unpacking glass substrates from a stack of glass substrates, and/or after a washing operation prior to fabricating an electrochromic stack on the transparent electronically conductive layer. Methods also include removing the sacrificial coating during a washing operation, during tempering, or prior to depositing an electrochromic stack by, e.g., heating the sacrificial coating or exposing the sacrificial coating to an inert plasma.

  • Publication number: 20210162719
    Abstract: Methods are provided for fabricating electrochromic devices that mitigate formation of short circuits under a top bus bar without predetermining where top bus bars will be applied on the device. Devices fabricated using such methods may be deactivated under the top bus bar, or may include active material under the top bus bar. Methods of fabricating devices with active material under a top bus bar include depositing a modified top bus bar, fabricating self-healing layers in the electrochromic device, and modifying a top transparent conductive layer of the device prior to applying bus bars.

  • Publication number: 20210001426
    Abstract: Thin-film devices, for example electrochromic devices for windows, and methods of manufacturing are described. Particular focus is given to methods of patterning optical devices. Various edge deletion and isolation scribes are performed, for example, to ensure the optical device has appropriate isolation from any edge defects. Methods described herein apply to any thin-film device having one or more material layers sandwiched between two thin film electrical conductor layers. The described methods create novel optical device configurations.

  • Publication number: 20190294016
    Abstract: Various embodiments herein relate to electrochromic windows that are bird friendly, as well as methods and apparatus for forming such windows. Bird friendly windows include one or more elements that make the window visible to birds so that the birds recognize that they cannot fly through the window. An electrochromic window includes one or more transparent substrates, wherein at least one of the substrates is an electrochromic (EC) lite including an electrochromic device and a pattern formed on at least one of the substrates by a laser, the pattern including a first feature configured to provide a set of optical properties different than optical properties of the transparent substrate. The set of optical properties includes one or more characteristics of refractivity, reflectivity and diffraction.
